Patented Dec. 30, 1930 PATENT OFFICE ALFRED FRANK, OF STU'ITGABT, GERMANY IRON-FRAME WALL FOR BUILDINGS AND THE LIKE Application filed February 28, 1928, Serial No. 257,740, and in Germany March 5, 1927.

arated by vertical and horizontal wall bars, will be, after the erecting of the panel- 10 framework, lined flushly inside and outside with stone or beton, and the panel surfaces on either side and beyond the wall bars are plastered over on the places where the flanged sides of the profiles lie free, by means of a i '15 plaster-bearer. The wall-bars, having the whole Wall width, and the flanges being exposed throughout their width, the construction is not absolutely fire-proof.

A further disadvantage resides in the fact '2 that the heaving-strength of the lining or betoning is not taken advantage of for it serves only as filling for the panels without helping to bear any of the strains or stresses to which the wall may be subjected.

' 2 In consequence a of the heat-conducting property of iron, damp places will be formed by moisture exuding along the flanges of the profiles, even when well plastered over. Finally the bars or scaffolding-poles, necessary for finishing up the wall with nogging-pieces,

are disadvantageous on account of the impracticability of fastening them to the wall when finishing it up.

All these disadvantages are overcome in carrying out the method of the present invention.

In the accompanying drawing two modifications of the invention are shown.

Figs. 1 and 2 are two vertical sections,

:40 Fig. 3 is a horizontal section through a larger part of the wall and Fig. 4 is also a horizontal section on an enlarged scale through a part of the doublebars;

" The invention contemplates the use of pairs increases considerably its fire-proof qualities. The double-girders a pass from the sleeperto the chief moulding; and between the inner surfaces 6 of the double-girders a pass the chases c, the nogging-pieces, the beams or the like, by which they also are joined together with U-shaped pieces (Z and the like.

The panels-formed by the doublesgirders a and the horizontal wall-bars 0, as shown in Figs. 3 and 4, are closely filled up with beton e or the like, to the out face of the doublegirders, in which the horizontal bars 0 are embedded and isolated on all sides, and the vertical girders on three sides by the filling mass 6.

The weight itself of the filling mass 0 capable of bearing after hardening, is transferred, without burdening the framework a,

0 on thebase walls passing bythe two horizontal bars 0, lying on both sides between the double girders. Thus the framework itself has only to bear the ceiling and roof-weights. The fillingsmass e of the framework forms in all directions, that is from the base-wall to the chief moulding, well as between the doublegirders a, a single vertical plate, capable of bearingand at the same time stiffening while in the hitherto building-method there were in this place only single and separated panels, not able to bear by themselves. Bolsters f and scaffolds are fastened directly to the wall bars a, as shown in Figs. 3 and 4,-by bolts 9 whoseheads are slidable in the dovetails of the girders a. a

The outer and inner wall plaster it enters directly in the dovetail of the double-girders 0, whereby a special fastening or a plasterholder is never necessary.

As the posts consist of two girders a separated from each other, an exuding of moisture therethrough is'eXcluded.

In the form of invention represented in Fig. 1 there is to be between the'girders a, an edge-way placed wood 0, while Fig. 2 shows in its place an I iron. While with the form of the invention shown in Fig. 1, on account of the total embedding of the edge-way placed wood a rather great security against fire is attained; this is consider- 100 ably increased by employing the embedded iron according to Fig. 2. V

It is advantageous to use light-beton as filler, but the use of gravel-beton, on ac-' count of its great capacity of bearing, is of special advantage too, inasmuch as self-bearing walls arise, as with iron beton, with. all their advantageous qualitiesonly with the difference that according to the present invention the armature-irons are at the same time themselves bearers for the wall 'mouldings in betoning. a
